IMPROVEMENT IN DRAUGHT-EQUALIZER. I

TO ALL WHOM IT MAY CONCERN:

Be it known that we, JAMES AVERILL, of Champlain, and ELISIIA S. FITCH,of Mooers, both in the county of Clinton, and State of New York, haveinvented a new and useful Improvement in Draught-Equalizer and Evener;and we do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of this specification, in whichi Figure 1 is a top view ofour improvement, as attached to a wagon-tongue, part being broken awayto show the construction. I

Figure 2 illustrates a slight modification of the same.

Similar letters of reference indicate corresponding parts.

Our invention has for its object to-furnish an improveddraught-equalizer, cvene r, or adjuster, for connecting thedraught-animals to the vehicle or other body to be drawn or moved, whichshall be simple in construction, and cfi'ec'tivein operation, alwaysgiving to the weaker or rear animal the longer arm of the lever; and itconsists in the construction of the double-tree, dranght-bar,orequalizer, and in the manner in which it is connected to the tongue ofthe vehicle, or to the body to be drawn or moved. I

A represents the tongue of the vehicle, which is constructed andattached to the said vehicle, or other body to be drawn, in the ordinarymanner. 13 is the equalizer or evener, the main part or body of which ismade in the usual form. To the straight front side of the evener, andequally distant from its ends, is securely attached,

by bolts, screws, rivets, or other convenient and substantial means, asegment, 6, of a circle, the centre of which is at the point, or nearthe point, at which is placed the hammer-pin O, by means of which thesaid equal izer is pivoted to the tongue'A. The {ace of the segment 6should be covered andprotected from wear by a. metallic strap or band,D, securely fastened tothe body of the equalizer by screws or bolts, asshown-in fig. 1.

To the rear side of the equalizer B, at its centre, is attached a longstaple, E, through the loop of which the hammer-pin C-passes, so as to,pivot the said' evenerto the tongue. F is a small friction-wheel orroller, the length of which equals the thickness of the equalizer B, andwhich works or revolves upon the pin or bolt G, which passes through itand through the tongue A. The upper end of the pin or bolt G issupported by astrap,

H, the rear end of which has a hole formed through it for the passage ofthe hammer-pin C, as shown in fig. 1, If desired, the rear end of thestrap H need extend no farther back than to overlap the upper side ofthe equalizer B, as shown in fig. In this case, the-forward end of thestrap H should be extended down to the tongue A, immediately in front ofthe roller F, and should be bolted or otherwise securely attached tosaid tongue, so as to strongly brace the pin G. In this case, thehammer-pin C may be permanently attached to the tongue A; and-theforward part of the staple, directly in the rear of the equalizer B, maybe enlarged, so that, when the equalizer has been drawn back, it may belifted from the toug.ue,-- the head of the said hammcr-pin,C passingthrough the enlarged part of said staple E. In all cases, .the' staple Eshould be so long that the loop of said staple cannot bear upon thehammer-pin C, so that the entire draught may be sustained by the rollerF and pin or bolt G.

Having thus described our invention, we claim as new, and desiretosecure by Letters Patent- 1. The combination of a curved segment, 5',with the central part of the forward side of the equalizer B,substantially as herein shown and described, and for the purpose setforth.

2. The combination of the friction-roller or ivheeltF and pivoting-pin Gwith the tongue A, and with the curved segment 6', to sustain thedraught, substantially as herein shown and described.

3. The combination of the strap H, or its equivalent, with the pin Gr,roller F, equalizer B, and tongue A, substantially as herein shown anddescribed, and for the purpose set forthi 4. The combination of the longstaple Ewi-th the equalizer B and hammer-pin C, substantially as hereinshown anddescribed, and for the purpose set.forth. v

5. Attaching'the equalizer B to the tongue A, substantially in themanner herein shown and described, so that the said equalizer may bereadily detached from the said tongue.

The above specification of our invention signed by us, this tenth day ofJanuary, 1868.
